In JAVA For statement is the most commonly used lopping statement which iterate over a range of numbers. It is different from if then else in a way that it forces the program to go back up again repeatedly until terminationexpressionevaluate to false. For loop is another way to control flo...
while and do-while. In this tutorial you will learn aboutfor loopin Java. You will also learnnested for loop, enhanced for loop and infinite for loop with examples.
Let’s look at the following examples: Print the output as: 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5 classNestedForLoop{publicstaticvoidmain(Stringargs[]){inti,j;for(i=1;i<=5;i++){for(j=1;j<=i;j++){System.out.print(j+"\t");}System.out.println();}}} Above program uses ...
Real-Life ExamplesTo demonstrate a practical example of the for loop, let's create a program that counts to 100 by tens:ExampleGet your own Java Server for (int i = 0; i <= 100; i += 10) { System.out.println(i); } Try it Yourself » In this example, we create a program...
2. Java For-loop Example In the following program, we are iterating over an array ofintvalues. The array contains 5 elements so the loop will iterate 5 times, once for each value in the array. int[]array=newint[]{0,1,2,3,4};for(inti=0;i<array.length;i++){System.out.format(...
import java.util.Scanner; class deadforloop{ public static void main(String[] args){ Scanner s = new Scanner(System.in); int a = 0;//记录正数的个数 int b = 0;//记录负数的个数 //for(;;){ while(true){ System.out.println("请输入一个整数:"); ...

Iteration is one of the most basic requirement in any programming language & of all, “for” is the most widely used loop in java for iteration. We will see the evolution of java for loop iteration techniques. 迭代是所有编程语言中最基本的要求之一,而“ for”是Java中迭代次数最广泛使用的循环...
In programming, loops are used to repeat a block of code. In this tutorial, you will learn to create for loop in C programming with the help of examples.
An important point to be kept in mind is that the type specified in the for-each loop must match the type of the elements in the collection because otherwise, there will be compatibility issues. Examples of For-Each Loop in Java Following are the different examples: ...
